Mushroom Laws by State 2026

States Where Psilocybin Mushrooms Are Legal for Medical Use

In some states, psilocybin mushrooms have been legalized for limited medical or therapeutic use under regulated programs. These laws allow controlled access to psilocybin in supervised settings, typically for treatment purposes rather than general use.

Oregon is currently the only state where psilocybin mushrooms are legal for medical use. In Oregon, access is limited to licensed facilities and regulated programs, and use outside of these frameworks remains restricted.

States Where Psilocybin Mushrooms Are Decriminalized

Some states have decriminalized psilocybin mushrooms at the state level, reducing or eliminating criminal penalties for possession and personal use. Decriminalization does not make the substance fully legal but typically lowers enforcement priority or replaces criminal charges with civil penalties.

Colorado has decriminalized psilocybin mushrooms statewide. In Colorado, possession and personal use are permitted within defined limits, though commercial sale and distribution remain restricted under state law.

States With Local Decriminalization Measures

In some states, psilocybin mushrooms remain illegal under state law but have been decriminalized in certain cities or local jurisdictions. These measures typically make enforcement of possession laws a low priority for local law enforcement rather than fully legalizing the substance.

States with local decriminalization measures include California, the District of Columbia, Massachusetts, Michigan, and Washington. In these states, specific municipalities have adopted policies that reduce penalties or deprioritize enforcement, while broader state-level prohibitions generally remain in place.

States With Active Research or Legislative Efforts

Some states have not decriminalized or legalized psilocybin mushrooms but are actively exploring changes through research programs or pending legislation. These efforts often focus on studying potential medical uses or considering future regulatory frameworks.

States with active research or legislative efforts include Connecticut, Maryland, Texas, Utah, Georgia, Illinois, Kansas, New York, Pennsylvania, Virginia, and West Virginia. In these states, psilocybin remains illegal, but ongoing studies or legislative proposals indicate potential shifts in future policy.
